Also see . . . Coal Mining -- Clayton Historical Society. It was the discovery in 1858 of a coal outcrop by W.C. Israel six miles south of Antioch and in 1859 of the Black Diamond Vein of coal by Francis Somers and James T. Cruikshank that created a furor. Coal found so close to San Francisco was vital to the growth of the California economy. It provided a cheap readily available source of the energy needed to fuel the foundries, mills, ferries, steamers and developing industries.
